I think Josh has done an amazing job with the Chilis, especially considering he thinks of himself as a drummer first. I love The Getaway and thought at the time they had indeed gotten away with it at last (losing John). I also think Josh's vocals complement Anthony's voice better than John's did.
Live, the Flea/John improv magic was definitely conspicuous by it's absence so looking forward to their telepathic connection again.
I'm really excited about John's return. Mega excited!
I just hope Josh is ok and has been treated fairly in this as he was, to me, a bona fide Chili Pepper, way more than just another stand in.
Without Josh I doubt there would even be a group for John to come back to.
